Answer:
12 dimes
Step-by-step explanation:
Let q represent the number of quarters. Then the number of dimes is 16-q and the total value is ...
0.25q +0.10(16 -q) = 2.20
0.15q +1.60 = 2.20 . . . . . . . simplify
0.15q = 0.60 . . . . . . . . subtract 1.60
q = 4 . . . . . . . . . . . divide by 0.15
16-q = 12
There are 12 dimes in the collection.
Answer:
Step-by-step explanation:
-9(-4w-v+5) = -9*(-4w) - (-9)*v + (-9)*5
= 36w + 9v - 45
10= 30 degrees 30+90= 120
11= 60 degrees 180-120= 60
12= 60 degrees 180-120 = 60
13= 120 degrees 180-60= 120
